Question: 1 / 1100

What is the bifurcation of the trachea called?

Trachealis

Carina

The bifurcation of the trachea is referred to as the carina. This anatomical feature marks the point where the trachea divides into the right and left mainstem bronchi, allowing air to enter each lung. The carina is significant not only for its role in the respiratory system but also in clinical settings, particularly during procedures such as bronchoscopy or intubation, where its location is critical for proper placement of instruments.

The trachealis refers to the smooth muscle and connective tissue that support the trachea but does not specifically denote the bifurcation point. The term mainstem bronchus refers to the individual passages that extend from the bifurcation of the trachea into each lung. The bronchial tree encompasses the whole branching system of the airways but does not designate the specific point of bifurcation.
